Moller told medical personnel she had a gun and wasn't afraid to use it, according to police.

Police said the Moller left her home, drove her white sport utility west on Ogunquit Road and crossed into Berwick when the vehicle hit a spike mat.

"The female exited the vehicle with a handgun. Pointed it at the officer and started to walk towards him. At the same time, an officer from York arrived on the scene. Shots were exchanged at that time and the female was taken to Portsmouth Regional Hospital where she was later pronounced dead," Bracy said.
